[Essai] Ubuntu installé seul en mode EFI : débridage UEFI
Attention : le débridage en question ne s'applique pas à tous les ordis de la terre. Il existe des fabricants qui ne brident pas le démarrage donc on n'a pas besoin de faire ça : Ubuntu démarre direct après installation. D'autres fabricants (dont HP) pratiquent le bridage du démarrage sur EFI/Microsoft/Boot/bootmgfw.efi de la partition EFI alors qu'ici il s'agit du bridage sur /EFI/Boot/bootx64.efi pratiqué par Lenovo, Toshiba (et peut-être d'autres)
But de l'essai : il existe une solution pour "débrider" proposée par maxire dans ce post mais elle présente l'inconvénient qu'il est nécessaire d'avoir recours à Super Grub2 Disk pour arriver à démarrer une session sur le Ubuntu installé afin de faire le débridage. Dans l'essai que je présente ici, je vais évaluer la solution alternative qui utilise Boot-Repair en mode "utilisation avancée".
Etat de départ (j'utilise VMware Player) : Ubuntu 14.04.1 installé en mode EFI. J'ai supprimé volontairement le dossier /EFI/Boot de la partition EFI afin de vérifier qu'il est bien recréé par Boot-Repair
1) Démarrage d'une session live Ubuntu 14.04.1 et installation de Boot-Repair : http://doc.ubuntu-fr.org/boot-repair#in … _de_ubuntu
2) lancement de Boot-Repair. sélection Utilisation avancée
3) paramétrage dans l'onglet "Main options" de Boot-Repair :
Il faut cocher la case "Use the standard EFI file", ce qui signifie que c'est le fichier /EFI/Boot/bootx64.efi qui va être créé par Boot-Repair. On notera en passant (ça se voit sur la vue) que c'est la version 4ppa17 de Boot-Repair qui est utilisée dans cette manip.
4) paramétrage dans l'onglet "Grub location" de Boot-Repair :
Normalement il n'y a rien à changer : il faut juste contrôler ce qui est présélectionné. Il pourrait y avoir des erreurs ou des choses à rectifier si plusieurs installations de Ubuntu ont été faites mais s'il y a eu une seule installation, en principe il n'y a rien à toucher. 
5) paramétrage dans l'onglet "Grub options" de Boot-Repair :
Il faut décocher la case "Secure Boot" ce qui entraîne que la case "Purge GRUB before reinstalling it" est automatiquement cochée. J'ai essayé dans une première tentative - que j'ai choisi de ne pas développer ici - de laisser la case "Secure Boot" activée mais la réparation ne fonctionnait pas : le fichier /EFI/Boot/bootx64.efi était un fichier "signé" et il semble que c'est pour cette raison que ça bloquait(*). 
6) lancer la réparation en cliquant sur le bouton "Apply"
7) après réparation, redémarrer l'ordi en n'oubliant pas de retirer le support live (LiveDVD ou LiveUSB) et ça doit redémarrer par défaut sur Ubuntu installé. Si ce n'est pas le cas, il faut intervenir dans le "Bios" (le système UEFI) pour mettre la priorité de démarrage sur le disque dur.
Depuis la session du Ubuntu installé, je peux vérifier que j'ai bien /boot/efi/EFI/Boot/bootx64.efi c'est à dire que Boot-Repair a bien créé lui-même ce lanceur. A noter qu'il existe aussi les fichiers grubx64.efi et shimx64.efi dans /boot/efi/EFI/ubuntu. Ces deux fichiers sont fonctionnels pour lancer Ubuntu installé mais ils ne sont pas utilisés puisque le démarrage par défaut de l'ordi se fait sur /boot/efi/EFI/Boot/bootx64.efi
A noter : à l'attention des experts, j'ai détaillé la manip dans le post #5 mais c'est juste pour ceux qui savent lire un rapport Boot-Info et qui veulent tenter d'analyser ce qui se passe.
(*) au sujet de la réparation "maxire", ce dernier signale dans ce post : "Une possibilité de réparation est de désinstaller grub-efi-amd64-signed (sinon problème de grub-rescue)", donc il y a bien un souci avec la version signée de Grub qui ne convient pas pour ce débridage UEFI.

Re : [Essai] Ubuntu installé seul en mode EFI : débridage UEFI
Salut Malbo,
N'y aurait-il pas une troisième alternative, sans Super Grub ni boot-repair ? Un truc de ce genre (adapté au numéro de la partition efi) doit aussi fonctionner, non ?

Re : [Essai] Ubuntu installé seul en mode EFI : débridage UEFI
@ikewdu : en théorie, ça devrait fonctionner.
Mon point de vue d'aujourd'hui, c'est que malgré qu'il faille utiliser Super Grub2 Disk (SG2D) comme dans ce cas récent, je vais continuer à proposer la méthode maxire plutôt que la méthode par Boot-Repair que je viens de tester dans le post #1. La raison, c'est que j'aime bien SG2D et je trouve utile de le faire connaître. De plus, quand le novice en galère arrive à faire démarrer son Ubuntu installé grâce à SG2D, il devient super motivé et confiant - il comprend qu'il a juste besoin de trouver l’ascenseur qui va bien pour atteindre sa piaule mais celle-ci existe et elle est est superbe - et il finit par obtenir son démarrage par défaut sur Ubuntu.

Bonjour,

Bah c’est grosso-modo le code exécuté par Boot-Repair dans la manipulation proposée ici par malbo.
Le seul avantage est que l’on ne risque pas d’être dérouté par les automatismes obscures de Boot-Repair (cf. la coche automatisée décrite au point 5).
Et je suis du même avis que malbo sur le fait que SG2D puisse redonner confiance et espoir au novice.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s
=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda1/efi/.../grub*.efi !

Unhide GRUB boot menu in sda2/boot/grub/grub.cfg
Boot successfully repaired.
You can now reboot your computer.On peut trouver cet extrait :
=================== User settings
The settings chosen by the user will purge (in order to unsign-grub) and reinstall the grub-efi of sda2, using the following options: sda1/boot/efi,
Additional repair will be performed: unhide-bootmenu-10s use-standard-efi-file rename-ms-efiOn y voit que j'aurais paramétré Boot-Repair pour demander le renommage des fichiers Microsoft (mention "rename-ms-efi") : grosse connerie puisqu'à la base il n'y a pas de fichiers Microsoft dans l'installation (voir le Boot-Info de l'État des lieux avant manip). C'est encore une manip sous-marine de Boot-Repair : ce n'est pas que ce soit grave mais ça brouille l'écoute. A cause de ça, j'ai refait plusieurs fois la manip parce que je croyais que j'avais laissé traîner des traces de Windows dans mon installation, avant de me rendre compte que c'est Boot-Repair de sa propre initiative qui crée de toute pièce la directorie /EFI/Microsoft/ et tout ce qu'il bourre à l'intérieur.
Dans cet autre extrait, on voit que Boot-Repair crée les fichiers .efi qui sont des copies du fichier /EFI/ubuntu/grubx64.efi de la partition EFI :
cp /mnt/boot-sav/sda2/boot/efi/EFI/ubuntu/grubx64.efi /mnt/boot-sav/sda2/boot/efi/EFI/Microsoft/Boot/bootmgfw.efi (& .grb)
df /dev/sda1
cp /mnt/boot-sav/sda2/boot/efi/EFI/ubuntu/grubx64.efi /mnt/boot-sav/sda2/boot/efi/EFI/Microsoft/Boot/bootx64.efi (& .grb)
df /dev/sda1
cp /mnt/boot-sav/sda2/boot/efi/EFI/ubuntu/grubx64.efi /mnt/boot-sav/sda2/boot/efi/EFI/Boot/bootx64.efi (& .grb)Le fichier qui nous intéresse dans la manip de débridage, c'est le fichier /EFI/Boot/bootx64.efi et là on voit écrit en clair qu'il est une copie du lanceur de grub (grubx64.efi)
3) Etat des lieux après manip :
Je fais un Boot-Info depuis la session du Ubuntu installé afin de pouvoir faire une comparaison avec l'état des lieux fait avant manip :

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of sda2, using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s
=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda1/efi/.../grub*.efi !

Cela constitue une validation du débridage puisqu'on sait que le démarrage sur le disque dur implique que le fichier /EFI/Boot/bootx64.efi de la partition EFI est utilisé pour le démarrage.
D'autre part, on peut constater - sans que ça ait une incidence dans la manip elle-même - que l'entrée Boot0001* ubuntu pointe sur grubx64.efi alors que si on va fouiller dans le Boot-Info avant manip pour la même entrée Boot0001* ubuntu, on peut voir qu'elle pointait sur shimx64.efi. C'est conforme à ce qui a été demandé puisque j'ai décoché la case "Secure Boot" dans l'utilisation avancée de Boot-Repair : le démarrage ne doit donc plus utiliser la version signée de Grub (fichier "signé" shimx64.efi)

Re : [Essai] Ubuntu installé seul en mode EFI : débridage UEFI
En complément, lors de l'utilisation de grub-install avec l'option --removable supprimez au préalable le répertoire EFI/Boot ou tout autre répertoire comme EFI/boot quelque soit la casse sinon le grub-install sera un échec sans message d'erreur particulier.
Sous Linux tous les répertoires d'un système de fichiers en FAT de nom identique à la casse près sont considérés comme localisés au même endroit.
En conséquence, la création d'un nouveau répertoire si il existe déjà sous le même nom avec une casse différente est impossible.
Il est peut-être possible de pallier à ce problème via l'option de montage du répertoire /boot/efi, je n'ai pas vraiment cherché, l'option de montage actuelle par défaut ne le permet pas.

Re : [Essai] Ubuntu installé seul en mode EFI : débridage UEFI
J'ai simplement lu la page Man de grub-install, vu que l'option --removable était apparue récemment et je l'ai testée sans trop comprendre ce que c'était, sa description étant succincte.
Le résultat sous Virtualbox a été le démarrage automatique de Linux en mode UEFI sans avoir à écrire un script startup.nsh.
Ensuite comme EFI/boot/bootx64.efi (à la casse près) correspond au programme lancé par le firmware UEFI lors de la sélection d'un périphérique au démarrage j'en ai rapidement déduit que cette solution pourrait être viable dans le cas notamment des Toshiba Satellite, les HP semblent plus tordus.
Plus besoin de copier manuellement grubx64.efi ou shimx64.efi dans EFI/boot/bootx64.efi.
Nous avons un vrai problème avec la documentation de Grub, celle qui est disponible à ce jour sur le site officiel n'est vraiment plus à jour ou bien absconse.
C'est d'ailleurs un problème général, je pourrais dire la même chose de Gnome et de Pulse Audio qui est sans doute la pire tellement elle est incompréhensible.

Re : [Essai] Ubuntu installé seul en mode EFI : débridage UEFI
@maxire : Il y a un truc qui ne plaît pas dans ta méthode : je viens de faire une mise à niveau(*) 14.04 vers 14.10 (en virtualisation) d'un Ubuntu auquel ta méthode avait été appliquée. Je constate que ça redémarre bien sur le disque dur - c'est à dire sur /EFI/BOOT/BOOTX64.EFI - mais je constate que ce fichier BOOTX64.EFI n'a pas été mis à jour lors de la mise à niveau. J'ai dû repasser la commande "sudo grub-install --removable" pour que le fichier BOOTX64.EFI soit mis à jour. Je n'aime pas ça parce que ça ressemble à ce qui se passe dans le cas des mises à niveau d'installation Ubuntu trafiquées par Boot-Repair (comme dans ce rapport de bug #1289977), c'est à dire que le fichier .efi n'est pas mis à niveau.
Du coup, je pense que pour ceux qui veulent installer Ubuntu tout seul dans l'ordi, je vais proposer systématiquement d'intervenir dans le "Bios" pour passer le "Boot Mode" en "Legacy" (non-EFI), de démarrer en session live Ubuntu, de créer une nouvelle table de partition MSDOS pour le disque dur avec Gparted, puis de faire l'installation en mode Legacy (non-EFI).
(*) mise à niveau "en ligne", c'est à dire par le "Gestionnaire de mise à jour".

Re : [Essai] Ubuntu installé seul en mode EFI : débridage UEFI
C'est une faiblesse de Ubuntu, lors d'une installation classique en mode UEFi aucun programme bootx64.efi n'est généré, donc pourquoi une mise à niveau s'en préoccuperait elle?
Je pense que tu arrivais tout de même à démarrer avec le programme bootx64.efi non mis à jour, as-tu comparé les deux versions via un md5sum par exemple?
Ceci dit, dans le cas d'une installation de Ubuntu seul avec possibilité de démarrer en mode Legacy, mieux vaut installer en mode Legacy.
Cela évite de se traîner ensuite une partition ESP dans laquelle pourraient s'empiler nombre de fichiers inutiles en cas de non maintenance probable de celle-ci par l'utilisateur.
Ce que tu indiques pourrait poser problème dans le cas des mises à niveau des dual-boot entre autres sur Toshiba Satellite lorsque grubx64.efi ou shimx64.efi ont été recopiés en bootx64.efi.

Tout à fait. Mais autant on peut tolérer les bricolages (copie de fichiers .efi) quand il s'agit de gérer la cohabitation délicates de Ubuntu et Windows 8, autant il n'y a pas de raison de supporter ça dans le cas où Ubuntu est tout seul dans l'ordi et que l'installation en mode Legacy est possible.
